Polling support for USB serial port adapters [patches]

[Hans Petter Selasky]

Hi,

Here is a patchset which you can try.

http://perforce.freebsd.org/chv.cgi?CH=168932

You need to download at least:

usb_serial.h
and
usb_serial.c

Download serial port drivers as needed.

You need to at least recompile all USB serial modules.

To enable you set:

hw.usb.ucom.cons_unit=0
hw.usb.ucom.cons_baud=9600

In /boot/loader.conf

NOTE: The patches have not been tested yet, only carefully reviewed. If you 
experience any problems, please debug and send patch to me.
